Abstract
778,422. Making tubes; rolling. STEWARTS & LLOYDS, Ltd. Dec. 14, 1955 [Jan. 3, 1955], No. 51/55. Classes 83 (2) and 83 (4). In a method of making rectangular or other non-circular section metal tubes f, Fig. 2, with thickened portions e a hollow body of circular section and uniform thickness is placed on a mandrel a, Fig. 1, and passed through a die such as a plurality of rollers c to form parts of unequal thickness and the resultant tube is then formed to the final section by drawing, rolling or pressing. The mandrel a may have flats b to form thickened portions which become convex areas e, Fig. 2, in the finished tube. In a modification the mandrel g, Fig. 3, is circular and the rolls form narrow portions on the billet which become concave sides m Fig. 4, in the finished tube.
